Check Digit Verification of cas no
The CAS Registry Mumber 931-34-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 931-34:
(5*9)+(4*3)+(3*1)+(2*3)+(1*4)=70
70 % 10 = 0
So 931-34-0 is a valid CAS Registry Number.

α-(Dialkylamino)-α-pyrrolylacetonitriles. A potpourri of useful synthetic transformations
Bray, Brian L.,Muchowski, Joseph M.
, p. 1305 - 1308 (2007/10/02)
α-(Dialkylamino)-α-(pyrrol-2-yl)acetonitriles (3) are versatile intermediates that are readily converted into regiochemically pure 2-bromo-6-dialkylamino-1-azafulvenes and 5-bromo-2-acylpyrroles (acyl= CHO, COR).In addition, 3 (R1= H), 4 (R1= H), and the β-substituted compound 9 are transformed easily and under mild conditions, via the corresponding α-methylthio compounds (e.g., 7a), into the methyl pyrrole carboxylates 8a, 8b, and 10, respectively.
