Check Digit Verification of cas no

The CAS Registry Mumber 131471-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,7 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131471-66:
(8*1)+(7*3)+(6*1)+(5*4)+(4*7)+(3*1)+(2*6)+(1*6)=104
104 % 10 = 4
So 131471-66-4 is a valid CAS Registry Number.

NEW ACYCLIC AND FUSED TRICYCLIC PHOSPHORUS COMPOUNDS AFFORDED BY NOVEL CONDENSATION

Zhang, Jing-Lin,Ma, Xiao-Bo

, p. 291 - 298 (2007/10/02)

The condensation of 1-(2-benzothiazolyl)-4-phenylsemicarbazide with (R2N)2PX (X = R2N, RO, Ph) proceeds with cleavage of the N-C(O) bond and formation of the title compounds which were also synthesized via similar treatment of 2-hydrazinobenzothiazole in good yields.Reactivities of (R2N)2PX, spectroscopic properties of the products and preliminary mechanism of these reactions were discussed.
