Check Digit Verification of cas no

The CAS Registry Mumber 878408-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,4,0 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 878408-58:
(8*8)+(7*7)+(6*8)+(5*4)+(4*0)+(3*8)+(2*5)+(1*8)=223
223 % 10 = 3
So 878408-58-3 is a valid CAS Registry Number.

A comprehensive approach to the synthesis of sulfate esters

Simpson, Levi S.,Widlanski, Theodore S.

, p. 1605 - 1610 (2007/10/03)

A comprehensive approach to the synthesis of sulfate esters was developed. This approach permits the direct and high-yielding synthesis of protected sulfate monoesters. Subsequent deblocking to reveal sulfate monoesters is accomplished in near-quantitative yield. The exceptionally stable neopentyl protecting group and the labile isobutyl protecting group were utilized in the synthesis of aromatic and aliphatic sulfate monoesters. Strategies for tuning protecting group reactivity were also explored and developed.
