Check Digit Verification of cas no

The CAS Registry Mumber 123130-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,3 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123130-63:
(8*1)+(7*2)+(6*3)+(5*1)+(4*3)+(3*0)+(2*6)+(1*3)=72
72 % 10 = 2
So 123130-63-2 is a valid CAS Registry Number.

A Scalable Protocol for the Regioselective Alkylation of 2-Methylcyclohexane-1,3-dione with Unactivated sp3 Electrophiles

Sharpe, Robert J.,Portillo, Maribel,Vélez, Robert A.,Johnson, Jeffrey S.

, p. 2293 - 2295 (2015)

A method for the C-selective alkylation of 2-methylcyclohexane-1,3-dione with unactivated sp3 electrophiles is accomplished via alkylation and subsequent deprotection of the derived ketodimethyl hydrazones. The present method provides a high-yielding entry to dialkyl cycloalkanones that cannot be accessed via direct alkylation of 2-methylcyclohexane-1,3-dione. The title reaction may be useful in the scalable preparation of terpene and steroidal building blocks in the arena of natural product synthesis.
